It appears the > connection will be retried forever, with the active never figuring out it's > no longer active. In my testing, the active-active state lasted almost 2 > hours with no sign of stopping before I killed it. The solution appears to > be to cap the number of retries or amount of time spent retrying. > This issue is significant because of the asynchronous nature of job > submission. If the active doesn't know it's not active, it will buffer up > job submissions until it finally realizes it has become the standby. Then it > will fail all the job submissions in bulk. In high-volume workflows, that > behavior can create huge mass job failures. > This issue is also important because the node managers will not fail over to > the new active until the old active realizes it's the standby. Workloads > submitted after the old active loses contact with ZK will therefore fail to > be executed regardless of which RM the clients contact. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
